This cop checks that models subclass ApplicationRecord with Rails 5.0.

Example:

# good class Rails5Model < ApplicationRecord # ... end

# bad class Rails4Model < ActiveRecord::Base # ... end

This cop looks for duplicate values in enum declarations.

Example:

# bad
enum status: { active: 0, archived: 0 }

# good
enum status: { active: 0, archived: 1 }

# bad
enum status: [:active, :archived, :active]

# good
enum status: [:active, :archived]

This cop checks for extra/unnecessary whitespace.

Example:

# good if AllowForAlignment is true
name      = "RuboCop"
# Some comment and an empty line

website  += "/bbatsov/rubocop" unless cond
puts        "rubocop"          if     debug

# bad for any configuration
set_app("RuboCop")
website  = "https://github.com/bbatsov/rubocop"

This cop checks for redundant return expressions.

Example:

def test
  return something
end

def test
  one
  two
  three
  return something
end

It should be extended to handle methods whose body is if/else or a case expression with a default branch.

Checks that exactly one space is used between a method name and the first argument for method calls without parentheses.

Alternatively, extra spaces can be added to align the argument with something on a preceding or following line, if the AllowForAlignment config parameter is true.

Example:

# bad
something  x
something   y, z
something'hello'

# good
something x
something y, z
something 'hello'

Use a guard clause instead of wrapping the code inside a conditional expression

Example:

# bad
def test
  if something
    work
  end
end

# good
def test
  return unless something
  work
end

# also good
def test
  work if something
end

# bad
if something
  raise 'exception'
else
  ok
end

# good
raise 'exception' if something
ok
